This patch extends the use of the brcmfmac driver with support for
chipsets with a USB host interface. The first chipsets supported are
the bcm43235, bcm43236, and bcm43238 for which firmware has been
submitted.
This driver change has been successfully built for x86, x86_64,
ppc64, arm_le, and mips_be.
It has been tested successfully on x86 and x86_64.
